15.8 How can you differentiate between addition and condensation polymerisation?
Addition Polymerisation- The process of repeated addition of monomer, having a double or triple bond to form polymers. For example, polyethene is formed by the addition polymerisation of ethene.
Condensation Polymerisation- Process of formation of polymers by repeated condensation reaction between two different monomers, having bi-functionality or tri-functionality. A small molecule is eliminated like water and in each condensation step. For example Nylon 6, 6 is a condensation polymerisation of adipic acid and hexamethylene diamine.
